Invoice clients for user research, journey mapping, wireframing, and usability testing. Get paid on time with Tidybill.
A UX designer invoice records fees for user experience research, interaction design, and usability work. UX projects span a broad range of activities including user interviews, survey design, journey mapping, information architecture, wireframing, prototype testing, and accessibility audits. Because much of this work is research and analysis rather than pixel-level output, clients sometimes underestimate the time involved. A detailed invoice that describes each phase of the UX process helps clients understand where their budget is going. UX designers often work as consultants embedded in product teams, so invoicing may be structured as a daily or weekly rate, or as a fixed fee for a defined research engagement.
| Service | Typical Rate | Unit |
|---|---|---|
| User Research (interviews, surveys) | £70 - £130 | per hour |
| UX Audit & Heuristic Review | £600 - £2,000 | per project |
| Wireframing & Information Architecture | £70 - £120 | per hour |
| Usability Testing (setup + sessions + report) | £800 - £2,500 | per round |
| Journey Mapping Workshop | £500 - £1,200 | per workshop |
| Participant Incentives (pass-through) | £30 - £80 | per participant |
UX work often involves a mix of fixed deliverables and time-based research activities. Invoice fixed deliverables (UX audits, usability testing rounds) as project fees, and ongoing sprint or retainer work at a daily or hourly rate. Pass through participant incentives and tool costs as reimbursable expenses with receipts. For multi-phase research projects, invoice at the end of each phase with a brief summary of outputs. Net 14 to Net 30 depending on client size. Senior UX consultants working with large organisations should request a purchase order before starting.
